Application filed January 21, 1909. Serial No. 473,560.

of the type adapted to display graphically. the

progress of agame of base ball, foot ball or the like. I

In my co-pending application Serial No, 448,530, I have illustrated one orm'of apparatus for the above purpose wherein is disclosed a field representation to be exposed to view, an indicator adapted to play over said field representation and operating instrumentalities associated with the indicator and spaced therefrom, conveniently to the rear of the field representation, whereby any movement imparted to the operating instrumentalities will result in a correspond ing movement to the indicator. The present invention is of this general type and contemplates certain developments and changes over said structure.

As inthe constructlon illustrated in the application above referred to, the present structure is intended to enable the operator position the indicator, which to properly conveniently takes the form of a ball, according to its position during each play of the game.

Primarily the present invention comprises as indicator, an operating device for the in dicator, and means whereby movement of the operating device a desired distance will result in a simultaneous movement of the indicator a difi'erent distance.

B the present construction, it is possible for the operator to be spaced from the field representation. and by moving the operating device over a diminutive guide or field representation cause an increase movement of the indicator over an enlarged field representation while at the same time the operating device and-indicator will assume corresponding positions on the guide I and the main field representation. In this way while an enlarged bulletin board with a relatively large field representation thereon may be made use of for the ready inspection of the public, the operating instrumcntalities are arranged in compact form and within easy reach of the arm of the operator in all of its positions of adjustment.

Further, the invention includes 'a field representation, a series of uides correspondmg to certain of the fie d representations at the rear of the field, a ball indicator adapted to play over the field, an operating device for the ball indicatorwith means for engaging and disengaging the operating device from the guides whereby the-op'erating device in its adjustment may follow sald guides to position'the ball accurately at certain points on the field representation, for instance the bases, or may be readily disengaged from said ides to impart movement of the ball indicator to any point of the field not provided for by the guides.

Other improvements and novel detailsin the construction and arran ement of arts will be pointed out in the description ereinafter, which should be read in connection with and will be readily apparent from the accompanying drawing forming "a part hereof and wherein a satisfactory embodiment of the invention is illustrated.

Reference. being had to the drawings, Figure. 1 is a front elevation of the field board with the apparatus applied thereto, Fig. 2 arear view of the same, Bi 3 is a vertical section of the board and t e indicator frame, Fig. 4 is a detail view on line i -4 of Fig. 3, Fig. 5is a similar view on line 5-5 of Fig. 3, Fig. 6 is an enlarged detail view of the operating device. Fig. 7 is asection on line 77 of Fig. 3, and Fig. Sis a detail view of the cord 14 and its connection with the operating shoe.-

In the said drawings, wherein like reference numerals designate corresponding parts throughout the several views, 1 is a bulletin board having upon its front surface a field representation, which, in the instance illustrated, is in the'form of a base ball field, thoughit is of course to be understood that any field representation may be disclosed. An indicator 2, conveniently shaped after the form of a ball, is adapted to play over the field representation in a manner to be described. A guide surface is provided for the'operating instrumentalities of the ball indicator, the guide surface preferably having an auxiliary field representation, and thoughthe same may be placed below the bulletin board proper or otherwise positioned, in thepreferred construction is arranged to the rear of the main field representation and may either constitute the rear surface of the board 1 or a supplemental board 3t-secured to the board 1 in any desired manner. The guide surface 3 with its field representation has a series of grooves or channels, which, for the purpose of illustration, extend from points representing the home plate and .pitchers box to the several bases, the object of said groovesv being to Y 6 are conveniently of metallic construction and formed with extensions 5 and 6 designed to extend to a point beyond the front surface of the board 1. The head blocks 5 and 6 are also channeled for the reception of a shaft 7 mounted for rotary-movement therein,and a wire or red 8 extending between the extensions of the head blocks constitutes a guide for the ball indicator 2, whichlatter has a central aperture whereby it-is sleeved upon the wire or rod for relative sliding movement. Upon one end of theshafts 7 at a point beyond the surface of the board 3 and within the'channelof the head blocks is a relatively small wheel 9, suit-ably a pulley which is fixed for rotation with the shaft while upon the opposite end of the shaft and within the channel of the head blocks is fixed for rotary movement with the shaft an enlarged wheel 10 which convenientlyv takes the form of a spirally grooved pulley. p I

11 is a cord, wire or the like secured at one end to the upper surface of the ball at 11 and at its opposite end in any desired manner to the upper spirally grooved ulley 10 as at 11*, the cord bein arrange to travel in said grooves. Secured to theunder surface. of the ball as at 12 isan auxiliary v cord, wire or the like 12 which is secured at its lower end as the upper cord 11, to the lower spiral grooved pulley 10 in the lower head block. The head blocks have apertures 11 for the passage of the cords 11 and 12. An operatingdevice in the form of a shoe 13 is slidably mounted in any de-' sired manner to the upright bars 4, the shoe 13 being suitably connected to impart rotary movement to the pulleys 9, and to play over the rear surface representation with the re- .sult that while the shoe is moved over the relatively small rear field representation to the desired point, owing to the diiference in the size of the pulleys Sand 10, the ball indicator 2 will be simultaneously moved a greater distance while since the main field representation is enlarged the ball indicator will assume a, position on its fi eld representa tion corresponding'to that position assumed by the operating shoe relative to the rear 1 representation. A cord, wire or the like 14 is secured in any desired manner as at 14* to the upper surface of the shoe-and extends upwardly passing over the upper pulley 9 thence downwardly through an aperture 15 in the shoe around the lower pulley 9 and upwardly to the lower surface of' the shoe 13 being connectedthereto as at 14*, it being noted-that the heads 5 and 6 are slotted as at 16 to provide openings for the cord 14.

From the description thus 'far it will be noted that asv the shoe is moved in either direction by an operating handle 17 projecting outwardly from the shoe, the cord 14 which has frictional engagement with the pulleys 9 will impart movement to said pulleys '9 and in turnto the enlarged pulleys 10 thereby winding or unwinding as the case may be the cord 11 about the spiral groove of said pulleys 10, with the resultthat the ball indicator will be accurately the supporting board 1. Conveniently this pivot is arranged adjacent the home plate of the rear surface representation.

Fitted within an annular recess of the shoe 13 is a hollow spindle 19 projecting outwardly from the shoe which latter has a collar 20 sleeved upon the spindle 19 and overlapping theterminal flange 21 of the spindle whereby the latter is held in place by screws or the like 22 engaging the collar and shoe respectively. The handle 17 is secured in any desired manner to the spindle 19 and may constitute-an integral part thereof. shaped to fit the grooves of the guides on the rear representation has an elongated extension 23 extending rearwardly therefrom and loosely passing througlr a central recess of the shoe 13 and through the spindle 19 and handle 17 to a point there beyond, ter minating in an operating knob 24. While the shoe through its extension is mounted for slidable movement relative to the spindle.19 the same is connected to said spindle for rotatable movement with the latter through the medium of a pin and slot c011- nection 25, it bein noted that the retaining collar 20 while ho ding the spindle in place A groove engaging member 22.

permits rotary movement ofthe latter. The pin and slot connection 25 just referred to limits the inwardand outward movement of the groove engaging device 22', and a ed for slidable movement on the bars 4 which latter are pivotally mounted, the groove engaging device 22-, by a slight pressure on the knob 24 will be moved into the guide grooves and adjusted along the guide grooves as desired and by reason of the fact that the device 22 has a relative rotary movement the same may adjust itself to the various grooves provided. It will be appreciated that since the operating device 22 is in engagement with the grooves it is possible to accurately position the ball indicator at the identical spot indicative of the respective bases for instance, or, wherever said grooves may extend. On 'the other hand should the pressure on the knob 24 be released the sprin will automatically release thedevice 22 from engagement with the grooves when the shoe may be adjusted to any point on the rearfield representation, with the result that the ball indicator will in turn assume any point on the main field representation. This is an important feature of the invention since it is obvious the ball may be quickly adjusted to any point on the field, and againfit may be positioned in substantially exact registration with the points provided for by the grooves, as the bases and pitchers box.

I desire it understood that while the present apparatus is illustrated as applied to a base ball field representation. many minor changes may be made' to adapt the apparatus to other uses in carrying out the principle'of operation.
